Невозможно перезапустить php-fpm в образе альпийского linux-nginx

Я пытаюсь заставить php работать на официальном образе докера nginx alpine linux nginx:alpine, В точке входа контейнера я запускаю скрипт, который делает что-то вроде:

rc-service -v php-fpm7 restart && nginx-debug -g "daemon off;"

но альпийский линукс продолжает показывать

ВНИМАНИЕ: php-fpm7 уже запускается

Я также пытался выполнить внутри контейнера rc-service -v php-fpm7 stop а потом rc-service -v php-fpm7 start, но я получаю почти такую ​​же ошибку:

ОШИБКА: php-fpm7 остановлен чем-то другим
ВНИМАНИЕ: php-fpm7 уже запускается

выполнив это случайное число раз, я получаю:

* You are attempting to run an openrc service on a
* system which openrc did not boot.
* You may be inside a chroot or you may have used
* another initialization system to boot this system.
* In this situation, you will get unpredictable results!
* If you really want to do this, issue the following command:
* touch /run/openrc/softlevel
* ERROR: networking failed to start
* ERROR: cannot start php-fpm7 as networking would not start
